18) باب ذِكْرُ أُسَامَةَ بْنِ زَيْدٍ

وَقَالَ نُعَيْمٌ عَنِ ابْنِ الْمُبَارَكِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، أَخْبَرَنِي مَوْلًى، لأُسَامَةَ بْنِ زَيْدٍ‏.‏ أَنَّ الْحَجَّاجَ بْنَ أَيْمَنَ ابْنِ أُمِّ أَيْمَنَ،، وَكَانَ، أَيْمَنُ ابْنُ أُمِّ أَيْمَنَ أَخَا أُسَامَةَ لأُمِّهِ، وَهْوَ رَجُلٌ مِنَ الأَنْصَارِ، فَرَآهُ ابْنُ عُمَرَ لَمْ يُتِمَّ رُكُوعَهُ وَلاَ سُجُودَهُ فَقَالَ أَعِدْ‏.‏
